我正试图通过ansible的帮助在ec2spot示例上建立一个定制的hadoop基础设施。在这样的示例中，只有内部ip是已知的。幸运的是，有一个 ec2.py 动态生成清单的脚本，可以配置为使用示例的完整外部dns名称作为 inventory_hostname . 所以我设置了所有要使用的jinja2模板 inventory_hostname 设置配置xml文件。到目前为止，对于hdfs和yarn，节点管理器也在资源管理器中注册。
但是，节点ID设置不正确，即设置为其内部ip地址。
我的yarn-site.xml.j2如下所示：

变量在哪里 resourcemanager_fqdn 是这样得到的：

{{hostvars[groups['tag_hadoop_resourcemanager'][0]].inventory_hostname}}
``` `tag_hadoop_resourcemanager` 是动态生成的主机组 `ec2.py` .
我以为节点id是从 `yarn.nodemanager.address` ，但这似乎被忽视了。只考虑端口9999。
这是一个错误还是我忘了设置一个额外的选项？
